FRIEDRICH AUGUST ANTONI, OF COLOGNE-EHRENFELD, GERMANY.

CORRUGATED PASTEBOARD WRAPPER.

Specification of Letters Patent.

Patented May 13, 1913.

Application filed November 2, 1911. Serial No. 658,247.

To all whom it may concern:

Be it known that I, Fnmnuron Auoo's'r AN'roNI, subject of the GermanEmperor, residing at Lichtstrasse 25, Cologne-Ehrenfeld, Germany, haveinvented certain new and useful Improvements in Corrugated Pasteboard IVzippers, of which the following is a specification.

Corrugated paste-board m'otective rolls, as hitherto known, consisteither of a single corrugated layer of paste-board or of two of suchlayers fastened upon a smooth intermediate baclcing. These protectiverolls, in order that they may be capable of being rolled up, are able tohave only one flat paper paste-board or cloth surface stuck upon oneside; the other side must remain unstuck, and the roll does not presenta good appearance on this side.

This invention consists of a protective wrapper made out of corrugatedpasteboard which can have a smooth paper pasteboard or cloth layer stuckupon its two outer sides without prejudicially affecting itsadaptability for being rolled up. This is accomplished by arranging twosingle corrugated paste-board layers which are pasted over on one sidewith their smooth sides outermost, and so that upon being rolled thecorrugations which project inward freely are prevented from engaging inone another by the interposition of a smooth loose inner layer whichseparates the corrugated faces from one another and provides a surfaceupon which they can rub. Obviously the two corrugated layers can consistof a single layer doubled over in the form of an endless band with thesmooth dividing layers between them. In order to prevent the twocorrugated layers from bending away from the middle layer, uniting meansare provided upon both faces secured to one of the corrugated layers orto the middle layer, holding the whole together in such a way as not toaffect its bending in either direction.

In the accompanying drawing two forms of the invention are shown.

Figure 1 shows the .wrapper consisting of the two corrugated paste-boardlayers IV I specially arranged with their smooth sides E outward, andthe loose separating layer F between them. The two layers IV IV are heldtogether above and below by ties V,

which are fastened to the middle layer F and engage in the outer side ofthe walls E or corrugations IV.

Fig. 2 shows the modification of the wrapper in which an endlesscorrugated band IV having the smooth surface I) outermost, is foldedaround the loose center layer F. In this form also ties such as V areused.

In Figs. 3, 41-, 5 of the drawings the invention is shown in the form ofa protective wrappershowing the corrugated layers movable in relation toone another, the right hand side of Fig. 3 showing a plan, and the lefthand side a horizontal section on line A-Ji of Fig. 4. Figs. It and 5are a vertical longitudinal cross section of Fig. 3 respectively. Inthis form a number of clamped shaped members U V shaped in cross sectionlike U are held together by cords or chains T, which are of a lengthcorresponding to the length of the wrapper. The two end members U arebow shaped and of a length corresponding to the length of the wrapper.The two end members U are how shaped and of convenient length to insurethe ends of the corrugated layers being guided within them. The centralmembers IE are shorter than the others, whose cross section. remainsalways the same, they grip around the edge of the wrapper above or belowin such a way that the two outer corrugated layers IV are pressedlightly against the smooth inner screen F, such corrugatcd layers IVbeing movable in relation to one another between the overlapped edges ofthe members. The members U V are secured to the inner screen F or to oneof the two outer walls II in any known manner.

II hat I claim is:-

A protective wrapper comprising layers of pasteboard having smooth andcorrugated faces and disposed with their smooth faces outermost, a layerloosely disposed between the juxtaposed corrugated faces, and meansmovably connecting said layers, substan tially as and for the purposesset forth.

In testimony whereof, I ailix my signature in the presence of twowitnesses.
